WILLIAM A. JORDAN, OE THIBODAX, LOUISIANA.

BRICK-MACHINE.

Specification of Letters Patent No. 15,766, dated September 23, 1856.

To all whom t may concern Be it known that I, W'ILLIAM A. JORDAN, ofThibodaux, in the parish of Lafourche and State of Louisiana, haveinvented certain new and useful Improvements in Brick- Machines; and Ido hereby declare that the following is a full, clear, and exactdescription ofthe construction and operation of t-he same, referencebeing had to the accompanying drawings, making a part of thisspecification.

The nature of myimprovement consists in arranging the tables A, and B,shoving heads e, and 7, actuated in the manner hereinafter to bedescribed, in combination with the rotary scrapers K, K, and curvedguards 0,0,said arrangement admitting of the attendants approach to theend of one of the tables from which the full mold is to be removed, andof depositing an empty mold on the adjacent table in a manner hereafterdescribed, while the rotary scrap-` ers perform the double function ofremoving the bulge or swell of clay in the mold in a superior `mannerand of depositing the greater part thereof in the empty mold.

The tempering and mixing of the clay is in the usual manner, that is theclay is moistened with water in a box, then thrown in the hopper, inwhich the knives or blades revolve and after being properly prepared itis forced through a grate by a revolving screw into the molds under thehopper.

The tables, two in number, A and B, are constructed with rails andguides, so that j the molds may be moved correctlythereon;

c is crank shaft placed below the tables. The two cranks on the shaft oare on the same side thereof so as to equalize the strain on the machineby having onelshoving head carry the molds forward, while the othershoving head is leaving the mold on the adjacent table and creating aIspace (a) for receiving an empty mold. Suitable motion is communicatedto the crank by a chain or band passing from pulley (b) Vto (d). Fromthe cranks are pitma-n rods t 71, connecting the shoving'heads: e, andf, therewith.

g g', are guide rods attached to the shoving heads. i

la, 7c are rotary scrapers, placed outside of the hopper, circularmotion is given them by belts, as indicated in the drawing, and theyserve the important ofice of removing the bulge or swell of the clay inthe mold which will rise therein after passing under the fixed scraper(usually employed) attached to the sideo-f the hopper. Also effectingt-he deposit of nearly all the surplus clay thus removed in the emptymold. The scraper la turning toward the scraper lo, the surplus clay isthus thrown within the revolution of the latter and by it assisted withthe curved guards O, O, deposited in the empty mold.' The `guards O, O,partially encircle the `Scrapers as shown in the drawing. It will benoticed that the action or operation of the scrapers 7c, 7c', isdivided, that is while 7c removes with a circular motion the excess ofclay from half the mold, that of 7a completes the removal and depositsit in the empty mold. By providing the curb (OQ) with a bottom to theoverhanging portion thereof, all dropping of clay other than in the moldwould be prevented. p

The operation is as follows: The attendant approaches a recess, formedby one of the tables projecting beyond the other, and with his left handdeposits an empty mold on the adjoining table while with his right handhe receives the full mold yfrom the table directly in front of him.

The feed of the mill being kept up and clay properly prepared in thehopper, the molds of one table, say of A, are forced toward the right bythe shoving head (e) coming in contact with the side of an empty moldplaced on said table, while it will be noticed that the shoving head (i)of the' adjoining table B, is retreating (on the right hand side) fromthe mold, by a previous movement carried under the hopper, thus creatinga space between the side of the mold and the retreating shoving head forthe reception of an empty mold on the right hand side of the machine.

By continuing the turning of the crank the shoving head of the table Aretract-s. thus leaving a space and the shoving head of B carries itsmold under the hopper, thereby enabling each of the workmen on the twosides of the machine, to place an empty mold on his table and offbear afull one with each revolution of the crank sh aft.

By my arrangement of reciproca-ting tables I entirely dispense with thewalking from one side of the machine to the other. consequent to theplacing the empty mold on one side of the machine and their reception onthe other.

In my description I have spoken of a single mold being employed, but ofcourse described, in combination with the rotary scrapers 7o, c, andcurved guards O O', the Whole being constructed and operated in themanner and for the purposes set forth.

In test-imony whereof I have signed my name before two subscribing`Witnesses.

VVILLIAM A. JORDN.

any number may be used, either in the breadth or length of the tables.

I do not claim broadly the use of double tables or the employment of arotary scraper as such devices have been used before, but v What I doclaim as my invention and desire to secure by Letters Patent is,

The tables A and B and shoving heads e and f", when arranged to operatein relation to each other in the peculiar manner above Witnesses:
